Excuse me while I try to wrap my head around the finale’s epic twists.

If you thought Derek’s killer was going to be the big reveal of The Lying Game‘s season finale — as I did — you were sorely mistaken. Though that discovery was shocking (and I’ll get to that), it was the March 5 episode’s final scene between Sutton (Alexandra Chando) and Rebecca (Charisma Carpenter) that caused my jaw to hit the floor hard. Actually, it’s still on the floor, which is making it very difficult for me to type this recap.

After being pronounced husband and wife, Alec (Adrian Pasdar) and Rebecca’s wedding received a few surprise guests: the police! Sutton and Ethan (Blair Redford) had discovered the infamous photo of Alec holding the murder weapon and turned into the police, which led them to discover the blood-stained tire iron at the Rybeks’ house. It’s still possible that he was set up, but for now, he’s off to the pokey!

Now for the real surprise: When Rebecca entered the room at the very end of the episode, Sutton greeted her with a chilling, “Hi, mom.” Yes, that’s right. “Mom!” I know we all suspected (slash assumed) that Rebecca was the twins’ mother, but hearing those words come out of Sutton’s mouth actually gave me goosebumps.

Even crazier? Rebecca’s response: “Great job, Sutton. Everything is going according to plan.”

That’s right, people. This whole season, Sutton was merely pretending not to know what was going on, when she was secretly working with Rebecca. This obviously leaves us with a million questions, though we’ll have to wait until season two to get them.

That is, if there is a season two!

What are your thoughts on tonight’s epic twist, Lying Game fans? Do you think Rebecca is really the twins’ mother? Do you think Alec really killed Derek? And, most importantly, do you think we’ll get a second season to sort all of this out? Hit up the comments section with your reactions. I’ll see you there!
